I GazINE PENCIL.

L Application filed June 6,

To all whom it may concern:

' Be it knownthatI, RoMoLo NARDI, a citizen of the United States, residing at Camden, in the county of Camden and State of, 6 New Jersey, have invented new and useful Improvements in a Magazine Pencil, of

which the following is a specification.

My invention relates to new and useful improvements in amagazine pencil, and has for its primary object to provide a plurality 'of lead holders any one of which maybe projected into writing position by a single pusher. Another object of this invention is to simplify and generally improve devices of this character so as to be simple in construction, relatively inexpensive in the cost of 'manu-- facture and positive in operation.

A further object of the invention is to construct a pencil of this class including two tubular members telescopically arranged and rotatable relative to each other, one of said members carrying a plurality of lead holders, spring actuated in one direction, and the other carrying a pusher adapted to be brought into endwise alignment with any one of said lead holders, due to the rotation of either of the tubular members and adapted to project the selected lead holder from the tip of the pencil so as to be in writing position.

With these ends in view, this invention consists in the details of construction and combination of elements hereinafter set forth and then specifically designated by the claims.

In order that those skilled in the art to which this invention appertains, may understand how to make and use the same, I will describe its construction in detail, referring by numerals to the accompanying drawin forming a part of this application,

Incarrying out the invention as herein embodied, 10 represents a tubular member or body carrying a tapered tip 11 preferably formed as an integral'part of the body'and having-a hole 12 at the extreme end. Intermediate the ends of the body are located a plurality of selecting lugs 13 projecting beyond the outer surface of said body and preferably produced by drawing them from the metal of the body walls. It is desirable that these selecting lugs be ,of considerablelength and arranged longitudinally of the body as shown particularly in Fig. 1 and adjacentthereto are designation marks or signs such as red, black and green, tBl e first mentioned one being shown at 14,

In the inner or upper end of the body is fixed a plate 15 preferably being set in a groove formed by slightly enlargin the inher end of said body as indicate at 16. The plate has a plurality of equally spaced holes 17 of greater diameter than thelead holders 18 which pass therethrough so that said lead holders are free to be moved side wise. Each lead holder has a sleeve 19 threaded on its outer end to adjustably hold a lead 20 in place, said sleeve having a por tion tapered as plainly illhstrated. Each lead holder also carries a guide 21 loosely fitting or surrounding and slidable on a rod 22 fixed to and depending from the plate 15, there being one rod for each lead holder.

About each rod is coiled a spring 23, one end resting against an enlargement at the lower or free end of the rod as the stationary element and the other end engaging a guide 21 as the movable element whereby the lead holders are normally held in a contracted position as shown in Fig. 2.

Onthe upper end of the body is telescop- 9 ically mounted a second tubular member or barrel 24, having a contracted lower end to snugly fit the body and produce an internal shoulder 25 for coaction with the enlargement 16 to prevent separation of the tubular members. In the smaller portion of the barrel are formed a plurality of longitudinal grooves 26 corresponding to the number of lugs 13 and lead holders. These grooves are adapted to register with the lead holder being guided to the opening by" lugs 13 and have offsets 27 which act as looking or holding means ,to hold the tubular members in collapsed condition when the lugs 13 are turned thereinto as shown in Fig. 3., One of the grooves 26 which is to be used as the selecting groove is designated by an indicating mark 28 and when the groove so marked is in alignment with a lug 13 the lead holder associated with such lug will be the one selected for use.

In the upper or outer end of the barrel is fixed a disc 29 carrying a depending pusher rod 30 offset from the longitudinal axis of the barrel so as to travel concentric with the plurality of lead holders in juxtaposition to the inner ends thereof and saidpusher rod is located adjacent the groove provided with the indication mark 28. The outer or upper end of the barrel is closed as by a cap 31 fitting over said end of the barrel and suitably secured in place. The

tubular members, or barrel and body, are normally forced apart by a spring 32 within the barrel and the ends engaging the plate 15 and disc 29. I

Ordinarily the parts are in the positions illustrated in Figs. 1 and 2, while not in use'but when it is desired to use any particular color of lead for writing purpose one of the tubular members is rotated relative to the other until the selecting groove having the indication marks 28 thereon aligns with a lug 13 associated with the lead holder carrying a lead of the colorthe tapered sides of the tip. As the selected lead holder is forced outward it must assume an angular or oblique position as shown in Fig. 3, for which reason the holes 17 in plate 16 have been formed considerably larger than the lead holders and the guides 21' have been given considerable play on the rods 23.

After the tubular members are telescoped sufiiciently to project the selected lead holder from the pencil top one of said members is rotated relative to the other until the lugs enter the oil'sets 27 which will hold the tubular members in telescoped condition while the pencil is in use. writer has finished using the pencil a slight Then When the 1 rotation of the tubular members will disengage the lugs from the offsets and the ac-' tion of the springs 32 and 33 will return the parts to their normal positions.

Of course I do not wish to be limited to the exact details of construction as herein shown as these may be varied within the limits of the appended claims without departing from the spirit of my invention.

Having thus fully described my invention, what I claim as new and useful is 1. A magazine pencil comprising a pair of telescoping tubular members, means for normally forcing said members apart, a plate fixed in one of said members, a plurality of lead holders slidably mounted in said plate, means carried by the other tubular member to force any one of the lead holders outward as the members are collapscd, and means associated with each of the lead holders for returning them to their normal positions.

2. A magazine pencil comprising in combination, a tubular body having a tapered tip at one end, a plate fixed in the opposite end, depending rods fixed in said plate, a plurality of lead holders slidably mounted and passing through said plate, guides carried by the lead holders and coacting with the rods, springs on said rods coacting with the guides to normally hold the lead holders in a contracted position, lugs on the exterior of the body corresponding in number to the lead holders and associated therewith, a barrel telescopically and rotatably mounted on the body and provided with a plurality of grooves at the inner or lower end for registration with the lugs on the body as said body and barrel are collapsed, said grpoves having ofisets associated therewith for coaction with the lugs to hold the I body and barrel in collapsed condition, an indication mark on one of the grooves to provlde one of said grooves for a selector, a pusher carried by the barrel and fixed with relation to the selecting groove whereby the rotation of the barrel Wlll move the pusher 1nto endwise alignment with a lead holder to be projected, and means within the barrel for normally forcing said barrel and body apart.

3. A pencil of the class described comprising a body having a tapered tip, lead holders fixed in said body for longitudinal sliding movement, abarrel telescopically and rotatably mounted on the body, a pusher fixed within the barrel so as to be moved into endwise alignment with the different lead holders during the rotation of the barrel, means for positioning said pusher relative to a selected lead holder whereby the telescoping of the barrel relative to the body will cause the selected lead holder to be proected beyond the ip, means to return the barrel to its normal position, and means as sociated with each lead holder to normally retain them in contracted ositions.

4. In a pencil, a body aving a tapered tip at one end, an enlargement at the other end forming a groove, a plate fixed in said groove, rods fixed to said plate, lead holders slidably mounted in said plate, guides carried by the lead holders and coacting with the rods, springs on said rods engagmg the guides to normally hold the lead ho ders in contracted positions, lugs formed from the side walls of the body and projecting beyond the outer surfaces thereof, a barrel having a restricted end producing a shoulder for coaction with the enlargement on the body to limit the movement of the barrel relative to said body in one direction, grooves in the restricted portion of the barrel for coaction with the lugs to position the barrel relative to the body for telescopic movement, means carried by the barrel to engage a single lead holder for projecting the latter beyond the pencil tip as the barrel is telescoped on the body, and means within the barrel to return it to its normal position. i

5. In a pencil, a body having a tapered tip at one end, an enlargement at the other end forming a groove, a plate fixed in said groove, rods fixed to said plate, lead holders slidably mounted in said plate, guides carried by the lead holders and coacting with the rods, springs'on said rods engaging the guides to normally holdthe lead holders in contracted positions, lugs formed from the side Walls of the body and projecting beyond the outer surfaces thereof, a barrel having a restricted end producing a shoulder for coaction with the enlargement on the body to limit the movement of the barrel relative to said body in one direction, grooves in the restricted portion of the barrel for coaction with the lugs to position the barrel relative to the body for telescopic movement, a disc fixed in the outer end of the barrel, a pusher rod carried by the disc and adapted to be moved into endwise alignment with any one of the lead holders by the rotation of the barrel, said pusher rod projecting the selected lead holder beyond the tip of the pencil as the barrel is telescoped, a spring within the barrel between the plate and disc for returning said barrel to its nomal posir tion and a cap enclosing the outer end of the barrel.

In testimony whereof, I have hereunto aflixed my signature.
